  • Paschen’s Law in Different Gases 

    Maves, Jackson; Hewitt, Brady; Campbell, Kathryn; O'Keefe, Ethan (2021-05-27)
    An experiment was performed to measure the Paschen curves of multiple gasses. Paschen curves are generated using Paschen’s equation. A plasma discharge tube was used to induce arcs of plasma in low pressure environments ...
  • Undergraduate Construction of an Optical Tweezer Apparatus with a Study of Brownian Motion on Micron-Sized Polystyrene spheres 

    Bisson, Yannich; Bucciarelli, Dean; de Lint, Maaike; Hasting, Daniel; Jafs, Michael; Reed, Madison (2021-05-26)
    In this experiment, an apparatus is designed for use with optical trapping of polystyrene spheres with diameters ranging from 1-5 µm. The goal of the experiment is to first construct a working apparatus that is capable ...
  • Optical Trapping: Final Report 

    Bisson, Yannich; Bucciarelli, Dean; de Lint, Maaike; Hasting, Daniel; Jafs, Michael; Reed, Madison (2021-05-26)
    The Optical Trapping experiment uses the momentum of photons from a laser beam in order to apply a trapping force onto 4.5 µm diameter polystyrene microspheres. When trapped in this way, the spheres behave much like they ...
  • Examination of low temperature argon plasma by optical emission spectroscopy and comparison with Paschen’s curve. 

    Micuda, Ashley; Lismer, Tristan; Ter Horst, Sam; Wormington, Reegan (2021-05-11)
    In this experiment we studied argon plasma at room temperature by varying the voltage and pressure of a plasma chamber for ten different samples. Our experimental measurements aligned with the theoretical optical emission ...
  • Temperature’s Effect on the Speed of Light 

    Xie, Anne; Chu, Jessica; Xie, Luyao; Zhao, Kun (2021-05-04)
    In this experiment, our group investigates the effect of temperature on the speed of light by experimentally measuring the change in the angle of refraction through common glass over a 100C range in temperature while ...
